Here you need to find the "unit rate," that is, the tuition cost per year:
<span>2 years of tuition costs about $7228 at pine tech. Write slope as cost per year (1 year)
Rise $7228
------ = ------------ = $3614 per year. This slope is POSITIVE, and the
Run 2 yr function for "tuition as a function of the # of years"
is linear and the relationship is proportional.</span>

Answer:</h3>
B) 7x - 1
<h3>
Step-by-step explanation:</h3>
In this question, you're going to solve by adding both f(x) and g(x) together.
You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.
What (f+g)(x) looks like:
(5x - 2 + 2x + 1)(x)
What you would do is solve to get your answer. You're going to be combining like-terms and adding.
When you're done solving, you should get 7x - 1
This means that B) 7x - 1 would be the correct answer.

Answer:
The answer to your question is Amy is correct.
Step-by-step explanation:
Data
Equation 2x² + 5x - 42 = 0
-Factor
2 x 42 = 84
- Find the prime factors of 84
84 2
42 2
21 3
7 7
1
84 = 2² 3 7
-Find two numbers that added gives 5
These numbers are 12 and -7
- Express the equation using these numbers
2x² + 12x - 7x - 42
-Factor by common factor
2x(x + 6) -7(x + 6)
-Factor by grouping
(x + 6)(2x - 7)
-Find the roots
x₁ + 6 = 0 2x₂ - 7 = 0
x₁ = -6 2x₂ = 7
x₂ = 7/2
5000:100=50. 50*4=200 5000-200=4800 do the same 5times more, always taking the last number, so now start with 4800:100....
Answer:
length = 16 yd, width = 21 yd
Step-by-step explanation:
A= l*w
336=l*w
w=5+l
336=l*(5+l)
l²+5l-336=0
l= 16, -21
length cant be negative so
l=16
plug l in to find w
w=21
